In the emergency of a fire or in the aftermath of a disaster, the struck area is rather difficult to access and may have become hazardous, hostile or toxic. Establishing whether the ground can be entered safely by human beings is time consuming. A major challenge is to quickly acquire and gather in situ data and forward information about the actual situation throughout the entire system. The Vi...

Information is lacking on ecosystem effects of understory burning in mesic mixed-oak (Quercus spp.) forests of the southern Appalachians. Native Americans used periodic fires in these forests for driving game and opening the forest. In April 1998, we conducted a lowto moderate-intensity fire in a cove–hardwood forest in the Nantahala National Forest, western North Carolina. In March 1998, befor...

Southern Appalachian forests are undergoing considerable change due to altered disturbance regimes. For example, fire exclusion has had a major impact on the structure and function of pine-hardwood ecosystems. Recently, fire has been prescribed for a variety of applications: 1) stand-replacement in the form of a mimicked wildfire, 2) site-preparation as part of a fell-and-burn prescription, and...

The sensor nodes in a wireless sensor network are normally microcontroller based which are having limited computational capability related to various applications. This paper describes the selection, specification and realization of a wireless sensor node using the field programmable gate array (FPGA) based architecture for an early detection of hazards (e.g fire and gas-leak ) in mines area. T...

Introduction . The fire resistance limits of load-bearing and enclosing structures can be identified using the method heat-and-mass transfer calculation in case fire. multifactorial nature nonlinearity problem makes application this complicated. If necessary, temperature regime, demonstrating conditions real fire, applied. In work, actual metal a thermal power station are calculated.Goals objec...

We assume that m facility units (hospital, bank, post office, fire department, police station, bus station, etc.) are requested to be established for n cities which are on the same line. We have to choose m cities where the facility units will be established such that total distance from all cities to nearest facility units is minimum. Here, it is supposed that the person who is in the city whi...

The aim of this study was to assess the regional effects of fire on the surface cover and forage production of mountainous rangelands of Delfan County, Lorestan province, Iran. The fire took placed in June 2007 with significant effects on the vegetation characteristics in the study area. Four fire affected sites were selected for sampling and a close area without fire was considered as control....

Soaring expenditures for fire management in the USDA Forest Service have caused substantial concern over fire management costs, especially in light of questions about the role of fire in ecosystems. This report contains analysis of most Forest Service fire management expenditures between fiscal years 1970-98. Expenditure information was obtained from a variety of sources, including electronic f...
